Problems solved by technology

Fairness between different systems operating in the same unlicensed band will not be guaranteed since base stations such as evolved Node Bs (eNBs) in LTE systems currently do not have the capability to perform measurements on unlicensed bands

Embodiment Construction

[0028] In the following description, for purposes of illustration and not limitation, specific details are set forth, such as specific circuits, circuit components, techniques, etc., in order to provide a thorough understanding of the present invention.

[0029] In the following description, the first method S100 performed in the base station eNB of the LTE system and the second method S200 performed in the UE are described and discussed, as well as a base station eNB suitable for performing the first method and a base station eNB suitable for performing The UE of the second method.

[0030] Throughout this specification, drawings and claims, the abbreviation eNB or LTE eNB is used to denote a base station eNB (ie as an eNodeB) in an LTE system. Herein a UE is any communication device operating in a radio frequency region, such as a smart phone, a notebook computer, a mobile terminal, a tablet computer, an iPad, and the like.

Abstract

The present exemplary embodiments relate to methods, an LTE eNB and a UE for enabling the use of a downlink carrier of an un-licensed frequency band. The eNB is adapted to configure at least one served UE to perform measurement(s) on the un-licensed frequency band and to report to the eNB. Based on the measurement report, the eNB decides whether or not to use the downlink carrier of the un-licensed frequency band. The embodiments also relates to a UE and a method in a UE.

Description

technical field [0001] The present technology relates generally to wireless communications, and in particular to methods and apparatus for enabling the use of unlicensed frequency bands in wireless communications networks. Background technique [0002] The massive growth in mobile broadband data traffic has driven the evolution of cellular systems to meet the huge demand for increased capacity. However, it will be difficult to solve the problem of traffic growth with the currently available spectrum of the Long Term Evolution LTE system (especially the valuable frequency band below 6 GHz with low propagation loss). From a quality and availability standpoint, licensed frequency bands (especially sub-6GHz) are superior, but also scarce and expensive. Given the fact that the amount of unlicensed spectrum currently equals the amount of licensed spectrum, and the fact that in some regions, more unlicensed spectrum is planned to be allocated, it is natural for operators to invest...
